If you are pregnant, the radioactive urea breath test for H. pylori is not usually done, because the radiation could harm your child.
When Will I Find Out the Results of the Urea Breath Test? The urea breath test is used to detect Helicobacter pylori (H. pylori), a type of bacteria that may infect the stomach and is a main cause of ulcers in both the stomach and duodenum (the first part of the small intestine).
Breath Test For Helicobacter Pylori: Diagnostic Tests.
The urea breath test is a rapid diagnostic procedure used to identify infections by Helicobacter pylori, a spiral bacterium implicated in gastritis, gastric ulcer, and peptic ulcer disease. It is based upon the ability of H. pylori to convert urea to ammonia and carbon dioxide.
A different test for H. pylori such as the breath test may need to be done as follow up to determine whether the infection is a current one. A negative test result means that it is unlikely that the individual has an H. pylori infection and their signs and symptoms may be due to another cause.
How are the results of the urea breath test interpreted? If the isotope is detected in the breath, it means that H. pylori is present in the stomach.
However, the test performance of persons under 18 years of age has not been established. There is also no established correlation between the number of H. pylori organisms in the stomach and the breath test results (Meretek Diagnostics, 2004).
This test uses a chemical reaction to detect the H. pylori bacteria. The test contains a chemical called urea, which is attached to a carbon atom.
A positive H. pylori status was based on positive culture performed both locally and centrally or, in the case of negative culture, a positive result for local histology and urease test (PyloriTek ). The non-invasive tests used were 13C-urea breath test (INFAI), serology (Pyloriset EIA, Orion), detection of H...
spectrometry, in 40 patients referred to monitor the ef®cacy of H. pylori eradication treatment. Results: Complete agreement was observed between the `gold standard' and the Breath ID test in 96.9% (94 out of 97) of the patients.
